When I see this kind of stuff, I think "previews of coming attractions." Makes you wonder what things will be like in the seven-year Tribulation after the church is taken up. It won't be pretty. From my reading of that period two basic things happen in the first 3 1/2 years. 1) Many get saved (none in the 2nd 3 1/2 years) 2) Half the earth is killed including all Christians.
This is definitely a preview. We are not to worry. The time is not yet and God will take us out when the time comes. In the meantime, we need to let His light shine so as many as possible come to Him.
I'm surprised you ever believed it.
